AI reads routine heart tests to predict artery blockages
NCT ID NCT06178900
First seen Aug 31, 2026 · Last updated Sep 01, 2026 · Updated 1 time
Summary
This trial tests whether an AI software called AI-Gatekeeper can help doctors predict if a patient has significant coronary artery narrowing (at least 50% blockage) using only routine tests like blood work, ECG, chest X-ray, and echocardiogram. About 450 adults with chest pain and low to intermediate risk of heart disease will be randomly assigned to receive the AI report or not. The goal is to see if the AI reduces unnecessary advanced imaging while still catching real blockages, and whether it is safe and cost-effective.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AI-Gatekeeper, a multimodal AI software that analyzes routine test results to predict coronary artery stenosis
- What this could lead to
- If it works, this AI tool could help doctors identify patients who need advanced heart imaging, reducing unnecessary procedures and costs.
- What could go wrong
- The trial is still early and the AI may not be accurate enough in all patients. It also depends on routine test quality, which can vary.
